I have what I've always thought - according to the music store that sold it to me ca 1971 (for $115.00) that my ES125 was a 1956. I can't find any SN on it, however... just a bare faint stamp that's unreadable in the top f-hole center.
I have the pick guard for the guitar but have lost track of the screws to remount it. Anybody know where I can get something like that? I checked the Gibson parts page with no luck.
I also need the cover for the headstock nut. There was one that came with the guitar, but it doesn't line up with the holes in the headstock.
